Why does water drip from the exhaust pipe after parking?

[AlexisFitz]

Water dripping from the exhaust pipe is a normal phenomenon. Here is some related information: 1. Some exhaust pipes have a drainage hole in the middle of the last section of the muffler or further inside. Water drains from here, so don’t mistake it for a damaged exhaust pipe—this is intentionally designed for drainage. 2. Regarding water dripping from the exhaust pipe, it’s important to note that the exhaust pipe is only connected to the cylinders and not to any other components. The cylinders cannot discharge liquid water; only exhaust gases are emitted. The water comes from these exhaust gases. Gasoline contains hydrogen (H), which combines with oxygen (O) to form water (H2O).
